Easier first steps

Arthritis and rheumatic aches often feel worst first thing in the morning or when the weather turns cold — and joints tend to loosen with warmth. Deep crystal heat, near-infrared light and PEMF give your hips, knees and back a gentle warm-up — or choose pure PEMF if you prefer no heat.

 
 
   

Ease arthritis and rheumatic aches with deep warmth

   

Deep, even heat for hips, knees and back.

       
     

What research shows

Heat is a long-standing, widely recommended self-care option for arthritis and joint stiffness. Red and near-infrared light have been studied for musculoskeletal pain, and TENS for pain relief across many conditions.

Why it works

Warmth increases comfort and makes tissue around the joints feel more flexible. Lying on a full-body mat warms several joints at once, and near-infrared light travels deeper than visible light.

Relevant wavelengths

  • 850nm near-infrared — deeper, toward joints
  • 660nm red — outer tissue layers
  • PEMF — gentle, adjustable pulses, with or without heat
